NetBSD-5.0 doesn't work

[Rapenne]

Hello

I'm using VirtualBox very often, this is the first time I report a bug for a software, I hope to make a "good ticket".

I just downloaded the netbsd-5.0 iso file, I verified the md5 checksum and it's right. I set up a virtual machine in virtualbox with a new virtual hard drive, no problem.

When I launch the machine, it start well, I can choose Install, Install no ACPI, Install no ACPI and no SMP or drop to boot prompt.

I tried the 3 first choices (normal, no acpi, no acpi/smp) and the problem is still here. I also tried to enable, disable, IO APIC, ACPI in the virtual machine option, doesn't work too.

The message I get during the boot is: (hope to make no mistake because I typed the whole message)

attimer0: attached to pcppi0
uvm_fault(0xc0b26cc0, 0, 1) -> 0xe
fatal page fault in supervisor mode

Stopped in pid 0.1 (system) at netbsd:spllower+0x28:     lock addl        %eax,0(%eax)
db{0}>

db{0}> is a prompt for something, I don't know exactly what I can do with this prompt.

I'm using Vbox 2.2.2 on a windows XP pro sp2 host, the cpu have no virtualisation feature.

I tried with another computer (windows 7 beta, 2x xeon 5420 with virtualisation activated) but I have exactly the same message.
